You don't need an aquarium have fun with these fish. These gummy swirly fish are brightly colored in red, green, orange and yellow and have a cool white swirl running through them. Each gummy fish is a bit 1.5" long from the top of it's head to big splashy tail. Sure, they may not be as healthy are real fish, but these delicious and soft and chewy. Perfect for colorful events or any time you want to chew on some sweet fish. Each kile (2.2 Lb) bag contains about 165 gummy fish, certainly enough for a big gummi aquarium.
